Abstract

The invention particularly relates to a corona discharge aerosol electrostatic neutralizer which comprises a neutralization chamber, an ionization chamber and a mixing chamber, the neutralization chamber is provided with an air inlet and an air outlet, an electrode needle and a grounding electrode are fixed to the ionization chamber, and the ionization chamber is provided with an air inlet and an air outlet. The mixing chamber is arranged between the neutralization chamber and the ionization chamber and is communicated with the neutralization chamber and the ionization chamber, the electrode needle is connected with a high-voltage alternating power supply, and the mixing chamber is provided with an aerosol inlet. According to the invention, rapid switching between unipolar ion generation and bipolar ion generation is realized by changing a high-voltage alternating power supply, and maximum probability neutralization of surface charges of aerosol particles is realized.

Description

technical field [0001] The invention relates to the technical field of electrostatic neutralizers, in particular to a corona discharge aerosol electrostatic neutralizer. Background technique [0002] The movement of microparticles generally exists in thermal engineering, atmospheric science, aerosol science, aerospace and other engineering fields. Such as the aggregation between particles, the collision between particles, the dispersion of particle clusters, the fluidity of particle clusters, etc. may have a huge impact on the entire industrial process. Therefore, the research on the motion characteristics of particles has important theoretical significance and industrial application significance. In particular, the research on the static electricity on the surface of particles is the focus of the above research. The force on particles during motion can be divided into the force on particles in the flow field and the interaction force between particles. The interaction fo...
